<h4 id="s1b">Introduction</h4> |
| 40 |
<p>The dump and restore commands are powerful tools that allow you to backup a live file system |
| 41 |
or to move data including permissions to another disk.</p> |
| 42 |
|
| 43 |
<h4 id="s1c">Migrating Data</h4> |
| 44 |
<p>Sometimes it is necessary to migrate data to a new hard drive. This can happen when one |
| 45 |
buys a bigger drive or a drive is failing. Here is a simple procedure to migrate data from |
| 46 |
/dev/ad0 to /dev/ad1. This assumes ad1 has already been partitioned (and labeled)</p> |

<code>mount /dev/ad1s1a /mnt</code><br /> |
| 50 |
<code>cd /mnt</code><br /> |
| 51 |
<code>dump -0 -f - /dev/ad0s1a | restore -r -f -</code><br /> |
| 52 |
|
| 53 |
<code>mount /dev/ad1s1e /mnt/tmp</code><br /> |
| 54 |
<code>cd /mnt/tmp</code><br /> |
| 55 |
<code>dump -0 -f - /dev/ad0s1e | restore -r -f -</code><br /> |
| 56 |
|
| 57 |
<code>mount /dev/ad1s1f /mnt/var</code><br /> |
| 58 |
<code>cd /mnt/var</code><br /> |
| 59 |
<code>dump -0 -f - /dev/ad0s1f | restore -r -f -</code><br /> |
| 60 |
|
| 61 |
<code>mount /dev/ad1s1g /mnt/usr</code><br /> |
| 62 |
<code>cd /mnt/usr</code><br /> |
| 63 |
